🔒 Paid game-license sales unlock after the contract audit. You can explore the form, but publishing is disabled for now.

List a Game

Add a game to the FlipKey marketplace. Players buy a license NFT and redeem it for a real key on the platform you support — Steam, Epic, Xbox, PlayStation, Nintendo, or your own in-house delivery. No upfront minting — the license is created at the moment of purchase, and your code hands over the key on redemption.

Licenses are issued on Ronin. Inventory is a counter — adjust the cap, price, or metadata any time without paying gas. Fields marked * are required.

Each item ticks off as you complete it. The Create Listing button unlocks when all five are green.

Platforms & Inventory

Add a row for each platform you sell keys on — Steam, Epic, Xbox, PlayStation, Nintendo, or your own in-house delivery. Each platform has its own cap, price, and redemption URL. Every redemption URL must pass a live link test before the listing can be published — your page handles a ?fk_test=1&nonce=… request and returns an HMAC-signed JSON response. See docs →

Template placeholders: {tokenId} (required) is substituted at mint time. {contract} (optional) is substituted with the contract address — use it if you sell across multiple ERC721 collections where token IDs may collide.

Region & Refunds

Where the listing appears in the marketplace. Doesn't lock the NFT itself.
Pre-redemption auto refund window. Default 14 (Steam-parity). Set 0 for no refund (promo / beta / collectible). Refunds before redemption don't waste a key — the slot returns to inventory, since nothing is consumed until redemption.

Tax

How this product is classified for sales tax / VAT. You're the merchant of record, so pick what best describes it — most game keys are “buy to own”.

License Terms (EULA)

Buyers can read this before they buy, and must accept it at checkout. Provide the agreement text, a link, or both — most marketplaces hide this; yours won't.
